ABSTRACT
OBJECTIVE:
To clarify whether the interferon-gamma (IFN-gamma) gene (IFNG) is associated with the histological phenotype of lupus nephritis.METHOD:
We analysed microsatellite polymorphisms located within the first intron of the IFNG gene to determine the genotypes of patients with lupus nephritis WHO class IV (n=24), patients with WHO class V (n=12) and healthy controls (n=61). We used flow cytometric detection of intracellular cytokines to identify CD4(+) T cells producing IFN-gamma. Production of IFN-gamma by peripheral blood mononuclear cells after stimulation with phytohaemagglutinin was evaluated with an enzyme-linked immunosorbent assay.RESULT:
The frequency of the IFNG allele 114 was significantly greater in WHO class V patients than in WHO class IV patients. Furthermore, the IFNG 114 +/+ genotype was more frequent in WHO class V than in WHO class IV patients. The level of IFN-gamma and the percentage of IFN-gamma-producing CD4(+) T cells were lower in individuals with genotype 114 +/+ than in individuals with genotype 114 -/-.CONCLUSION:
The IFN-gamma gene is associated with the histological phenotype in lupus nephritis.
